Mas

Mas is a resistant Sianat who was cured from the Whisperer, making her a Solitary. She appears in The Long Way to a Small, Angry Planet, and in the short story A Good Heretic.

A Good Heretic
Mas was born on the Sianat homeworld and infected with the Whisperer during childhood. While the virus affected her body and gave her the ability to Navigate, it did not affect the way she viewed herself or the world around her. Mas kept this quiet out of fear, and did her best to blend in with the Pairs around her.

Mas trains to be a Navigator and gets a job on a Harmagian tunnelling ship. The traditional Sianat lifestyle makes her unhappy and eventually she confesses in Lum'matp, her captain. When the Wane sets in, Lum'matp takes her to Arun, where Mas receives the cure and becomes a Solitary.

The Long Way to a Small, Angry Planet
Ashby and Kizzy meet Mas when they contact the colony for a small piece of tech. Mas introduces them to the idea of a cure for Ohan, who is Waning.
